ATIURNEY-S Patented Aug. 14, 1951 UNITED STATES PATENT OFFICE 2,564,147 VALVE Leiinard C. Bowling, Houston, Ten. Application March 9, 1946, Serial N o. 9 Claims. (01. 25i 10'1) 1 This invention relates to new and useful improvements in valves.

One object of the invention is to provide an improved valve involving a partially rotatable valve member including an elastic portion arranged to undergo deformation when turned to- Ward a closed position, whereby said portion expand's the jacket 'znember's into fluid-tight engagement with the inner wall of the valve housing when the valve is shut off. v

A further object of the invention is to provide an improved valve having a partially rotatable valve memberincluding a deformable core having external members and arranged so that one or more portions of the core are exposed for packing off the valve housing; together with means for deforming said core to expand the external members into fluid-tight engagement with an inner annular wall of the valve housing, when the valve member is turned.

Another object of the invention is to provide an improved valve having a partially rotatable valve member includin a deformable core enclosed within arcuate resilient jackets, terminating short of the ends of the core; togol hr with means for holding the core under suflicient deformation to cause the projecting ends thereof to engage the inner annular wall of the valve housing and pack off the same, also whereby,

turning of the valve from an open to a closed position will cause further deformation of the core to expand said jackets into fluid-tight engagement with the housing wall.

Still another object of the invention is to pro; vide an improved valve having a' ShUtJ JITlIlGmbBI' 1 including arcu'a'te external members enclosin an elastic body and a telescoping conductor attached to the external members and extending through said body, whereby the body may" be deformed and the members expanded without disconnecting the conductor.

A construction designed to carry out the inven} tion will be hereinafter described together with other features of the invention; 7 V

The invention will be more readily understood from a reading of th following specification and by reference to the accompanying drawings, wherein an example of the invention is shown, and wherein: I

Fig. 1 is an isometrical view of a valve constructed in accordance with the invention, 7

Fig. 2 is an isometrical view partially'in elejva tion and partially inse'ct'ion, showing the valve in its open position,

Fig.3 is a horizontal cross sec'tion'al View of the valve below its in its shut-oil position, Fig. 4 is a horizontal crols's se ctional view of the valveatits central portion and in its open position,and J V I Fig. 5 is a plan view bi the valve, thehandle closure being omitted and the connecting rods being shown in section. I In the drawings, the numeral I Qde sie'na tes a cylindrical valve housing open at each itstop and bottom and providedv at its mid-*heightwith diametrical opp'o'sit'enippls Land .12, which are internally screw-threed'ed and project outwardly therefrom. Within the hou'sin'g a partially rotatable valve memberA is mounted. Thismember is cylindrical and iitl'lds through the major portion of the hous ng. The inernberincludes acy; lindric'al elastic core 14 en'clo'sedwithin elongate metallic jackets l3 which are substantially semicircular in crosss'ection p p The core maybe made 9t rubber, synthetic rubber or other deform'able material, suitable for the purpose. The jackets arepreferably made of rel atively thin resu entme a and itis desirable to bond them to the cpr'e. vfrh'e Vertical edges of t e jackets are spaced apart soihciently to permit said jaclgets to undergo radial contraction. Flow tubes l5 hav l theii' outer ends secured in the niedial portions of the jackets and flush with the outer surfaces thereef. The inner ends of these tubes telescope a sleeve is and thus form a telescoping conductor adapted to register with the nipples H and |2.- v I A c'ylindrical plug ms provided with a flat cylindrical boss l8 whichtelescopes thebottom of the housing Ill and contacts the bottom of the valve member A. ,The parts are so proportioned thatwhen the' valve is in its open position as shown in Fig 2, the flanged portion of the plug, which extends outwardly from the boss 18, is spaced below the bottom edge of the housing, thereby permitting the plug. to undergo a, slightly upward movement befpre engaging with the. housing. As the rem-ar na of the core {4 projects below the lower edges of the jackets 13, a narrow annular band B of the core is exposed and t his band is extruded sufficie'ntly to engage the inner. annular wall of th housing and form a pack-off ring. It is pointed out that even in the open position, the core'is' spific iently deformed to produce a snug" turning fi t between the jackets and the wall of the housing and this will permit thehand B' to extend under the edges of the jackets and at the saiifne tirne hold the plug l! slightly spaced frdiil e ottornl de I t e l na. A fiat circular follower'disk I9 is inserted in the upper end of the core whereby an annular packing band C similar to the band B is produced. The upper surface of this disk lies substantially flush with the upper annular edge of the housing. Elongate connecting bolts 29 extend upwardly through the plug, core and disk, being disposed transversely to the longitudinal axis of the tubes I and sleeve IE on each side of the latter, as is best shown in Fig. 4. These bolts have heads 20' on their lower ends engaging the under side of the plug IT.

A circular head 2I forming part of an operating member is provided with a radial handle 23. The diameter of the head is substantially the same as the external diameter of the housing I0, and it is adapted to rotate on the upper edge of the housing and upon the upper flat face of the disk I9. The head 2I is formed with arcuate slots 22 radially disposed so as to receive the upper ends of the bolts 20, whereby the head may be rotated with respect to the bolts and the housing. Upstanding arcuate cams 24 are provided on the upper face of the head 2I contiguous to the slots 22 and each carn includes oppositely directed faces 25 inclining upwardly from its central portion. A pair of nuts 25 are screwed onto the upper screwthreaded ends of the bolts 20, the upper nut acting to jam the lower nut in its adjusted positions.

When the valve member A is in its open position, as is shown in Fig. 2, the lower nuts 25 rest at the central or lowest portions of the earns 26. Since the head 2I is mounted to rotate on the upper edge of the housing I0, free of the core I4, jackets I3, disk I9 and bolts 20, it is obvious that there must be some positive connection between said head and the core elements to contribute rotation to the latter when said head is rotated. Further, when the core I4 is retracted or unexpanded, the resilient jackets I3 will be unexpanded and free to rotate in the bore of the housing. The nuts 25 resting in the center of the cams will not ride up said cams upon initial rotation of the head because the frictional resistance oifered by said cam is greater than any frictional resistance which might be offered by the jackets I3 and core I4, due to the lack of contact of said jackets with the housing wall. When the handle 23 is first swung, the valve member will be rotated. In order to provide a positive stop to arrest such rotation, the disk I9 is formed with an arcuate recess 21, in its periphery, adapted to receive a lug 28 on the bore of the housing projecting into the recess. These elements will arrest rotation of the valve member A at a full open position and a fully closed position. When the lug engages one end of the recess and rotation of the member is stopped, the nuts will then ride up the cam 26, lift the bolts 20 and expand the core I4 and the jackets I3 into a metal-to-metal contact with the bore of the housing.

It is pointed out that a relatively slight degree of deformation of the core I4 and expansion and contraction of the jackets I3 is involved in the operation of the valve. When the valve is in either its open position or in its shut off position, it is obvious that the initial movement of the handle 23 will break the frictional seal betweenthe jackets and the housing and after this is done, on y sufilcient clearance is necessary to rotate the valve member A to its full open position. The breaking of the frictional seal is due to the fact that the amplified area of the metal-to-metal contacts between the jackets I3 and the wall of the casing is greater than the frictional resistance of the cams, when the direction of rotation of the head 2I is reversed. While the core and jacket has been illustrated as having a moderate height, it is obvious that the valve could be shortened vertically if desired. The use of the deformable core I4 obviates numerous sliding metal parts commonly used in this type of valve and makes for a very simple, and comparatively inexpensive, structure.

The valve is easy to operate and the conductor formed by the tubes I5 and sleeve I5 shields the core from contact with the fluid passing therethrough. The jackets I3 shield the cylindrical surface of the core from the fluid and provide smooth operating surfaces as well as protecting the core against wear. Due to the fact that the head member of the handle 2| is not positively connected to the valve member A, the plug I! and the disk I9, said head member is independently movable and thus if the frictional engagement between the jackets I3 and the wall of the housing was of such degree as to resist the initial opening movement, the frictional engagement between the nuts 25 and the faces 26 of the cams would be broken upon initial operation of said head, and this protects the elements enumerated, as well as the bolts 29, against injury. It also provides for a final tightening movement at the end of the shut off operation.

The foregoing description of the invention is explanatory thereof and various changes in the size, shape and materials, as well as in the details of the illustrated construction may be made, within the scope of the appended claims, without departing from the spirit of the invention.
